You have to know a few things about energy first.
Heat is the amount of energy in a substance.
Temperature is the average amount of heat in a substance.
The ocean may be 50 degrees Fahrenheit, and we may 98.6F, but the ocean has far more heat than we do. The ocean is extremely large, and has a lot more heat, and we're so small and only have a tiny bit in our body.
Temperature is the average, so we can be "hotter" than the ocean because on average, our body has more heat per volume.
Energy is required to move the molecules in your room, bath water, chicken dinner, to raise the average amount of energy, so it's heated by definition.
energy. and patience. :)
If you are asking why a green heating system will not go above 68 degrees Fahrenheit then one reason is to save energy. The higher the temperature the more energy required to get to that temperature and the more energy required to keep that temperature.
If a house is in a cold environment, more energy may be required for heating. And if it is in a dark place (say, between mountains, or in a cloudy area), more energy may be required for lights.
To calculate the total energy required, we need to consider the energy required for each phase change using the specific heat capacities and latent heat of fusion/vaporization. The energy required can be broken down into: heating the ice from -30°C to 0°C, melting the ice at 0°C, heating the resulting water from 0°C to 100°C, boiling the water at 100°C, and heating the steam from 100°C to 140°C. The total energy can be calculated using these components.
No, heating a flask on a hot plate is not an example of activation energy beginning to react. Activation energy refers to the minimum amount of energy required for a chemical reaction to occur, and it is not related to heating a flask. Heating a flask on a hot plate simply refers to the process of applying heat to the flask, which can facilitate a reaction by increasing the temperature and providing the necessary energy for the reaction to proceed.
for every reaction there is a minimal amount of energy required. sometimes this amount of energy is provided by the environment and sometimes not. when the energy is not provided by the environment heating is required. all of this is a result of the collisions of atoms .they need energy to form products with other atoms. this energy is obtained from the environment
That is related to energy required for heating. If you require energy to keep your house warm, a draft can take energy out - replacing hot air with cold air. This will require more heating. In summer, the situation is similar - except that the wasted energy is related to air-conditioning, and that cool air will be replaced with warm air.

heating it
Geothermal energy produces heat energy from within the Earth's core. This heat energy is harnessed to generate electricity or for direct heating purposes like hot water heating or space heating.
Energy usage typically increases during extreme weather conditions, such as summer and winter, due to increased demand for heating and cooling. In summer, energy is often used for air conditioning, while in winter, it is required for heating. Spring and fall usually see lower energy usage as the temperature is more moderate.
Yes, the amount spent on heating is typically higher when temperatures are colder because more energy is required to maintain a comfortable temperature indoors. As temperatures drop, the heating system needs to work harder to compensate for the heat loss, resulting in increased heating costs. Conversely, in warmer temperatures, less energy is needed to keep the indoor temperature comfortable, leading to lower heating expenses.
